Tsvagiridzo yesainzi inoratidza kuti nitrogen yakawandisa inopinda mumvura inokonzeresa eutrophication yemuviri wemvura uye inokanganisa kunaka kwemvura yemuviri wemvura kune imwe nhanho. Zvido zvekuChina zvekutonga zvakatipoteredza zvekumaruwa zviri kuwedzera gore rega rega, nekuti nyika yangu yekubvisa tsvina yetsvina A-level yakajairwa yekubuda ine zvirambidzo zvakasimba pane zveN content, uye masampula etsvina yekumaruwa anewo zvimwe zvinodiwa zvenitrogen. Nhasi, Liding Environmental Dziviriro ichaunza muchidimbu tekinoroji yakakwidziridzwa denitrification kwauri.
Enhanced denitrification tekinoroji inoreva kuvandudza kugona kwekushatisa kwenitrogen-ine makomisheni, kuwedzera mwero wekuderedzwa uye kuvandudza kunaka kwetsvina nekurapa iyo microbial chimiro, kuwedzera emuviri nemakemikari nzira uye kugadzirisa maitiro panguva yekusvibisa maitiro. Biological denitrification mukurapwa kwetsvina yakwezva pfungwa dzevanhu, asi maitiro ekuita zvinobudirira kurapwa kwe denitrification ichiri dambudziko rakaoma mukurapwa kwetsvina.
Bio-enhanced denitrification tekinoroji inoshandiswa zvakanyanya mukuchenesa tsvina yekumaruwa. Nekuwedzera mabhakitiriya chaiwo, zvinovaka muviri kana substrate analogues kune biological kurapwa, iyo biomass mukurapwa inogona kuwedzerwa, kugona kwekuora kwemuviri kune zvakasvibiswa zvinosvibisa kunogona kuvandudzwa, uye mwero wekuderera unogona kuvandudzwa, saka unogona kuzadzisa chinangwa chetsvina. kurapwa. Iyo tekinoroji ine maitiro emutengo wakaderera, kuita kwepamusoro uye kusvibiswa kwakaderera. Pamusoro pemaruva echinyakare, tupukanana twakanyatso pindira mu nitrogen cycle muzvisikwa zvinosanganisira anammox bacteria, aerobic denitrifiers, uye denitrifying phosphorus-kubvisa mabhakitiriya uye mamwe akakosha nitrogen-metabolizing microorganisms.
Kuti ive nechokwadi chekuti kuburitswa kwe nitrogenous komisheni mumvura yetsvina inosvika pachiyero, zviyero zvakaita sekuwedzera chiyero cheaeration chechimiro, kuwedzera hydraulic retention nguva, kuwedzera sludge reflux ratio, kuderedza sludge mutoro, kugadzirisa tembiricha yekuita. , kana kuwedzera ukobvu hwekuzadza kunogona kushandiswa mupurojekiti. Nekudaro, maitiro aya achawedzera mari yekuvaka nekushanda kwenzvimbo dzekuchenesa tsvina, zvichikonzera kukanganisa kukuru kwehupfumi. Kunyangwe physicochemical nzira yakakwidziridzwa denitrification tekinoroji yakagadziridzwa kare, kune matambudziko akadai semutengo wakakwira, nyore kugadzira disinfection by-zvigadzirwa, uye kusvibiswa kwechipiri. Yakajairika mitsva yakagadziridzwa denitrification maitiro anosanganisira pfupi-range nitrification-denitrification process, heterooxygenation-aerobic denitrification process, aerobic granular sludge, pfupi-range nitrification-anammox process, nezvimwe.
Ndizvo zvese zvenyaya iyi, kune zvimwe zvirimo, ndapota teerera kugovera kwaLiding muchikamu chinotevera. Liding Environmental Dziviriro yakazvipira dhizaini, kutsvagisa nekusimudzira, kugadzira uye kushanda kweiyo decentralized sewage treatment system michina munzvimbo yeindasitiri yezvakatipoteredza kwemakore gumi. Kuvimba nehunyanzvi yakamisikidzwa uye modular otomatiki mitsara yekugadzira, Liding zvigadzirwa zvine mabhenefiti ari pachena mumhando nekuita. Midziyo yekuchenesa tsvina yemumba yakazvigadziridza inogona kushandiswa zvakanaka kunzvimbo dzakapararira dzekumaruwa. Kana iwe uchida mhinduro dzechigadzirwa uye zano rehunyanzvi, unogamuchirwa kubvunza. Webhusaiti yedu ndeye: www.lidingep.com whatsapp: +86 19951179575
